Bug ID: 119575
Summary: ICE parsing expression with overloaded operators
Product: gcc
Version: 14.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: rnhmjoj at eurofusion dot eu
Target Milestone: ---
Compiling this program:
1 module myint_mod
2
3 type myint
4 integer :: n
5 contains
6 procedure :: add
7 generic, public :: operator(+) => add
8 end type
9
10 contains
11
12 pure function add(p, q) result(r)
13 class(myint), intent(in) :: p, q
14 class(myint), allocatable :: r
15 r = myint(p%n + q%n)
16 end function
17
18 end module myint_mod
19
20 program main
21
22 use myint_mod
23
24 type(myint) :: p, q
25
26 p = myint(3)
27 q = (p + p)
28 print *, q
29
30 end program
results in the following error:
f951: internal compiler error: Segmentation fault

char const*, __va_list_tag (*) [1], diagnostic_t)

0x86f2ef gfc_be_parse_file()

I tested on GCC 13.3.0 and 14.2.1, both give the same error.
Notes:
1. The program compiles and runs correctly after removing the parenthesis at
line 27.
2. The same crash happens in ifort, but not ifx.
